Which of the following are functions of the cranial bones?
The main function of the bones of the skull along with the surrounded meninges, is to provide protection and structure.

Structurally it provides an anchor for tendinous and muscular attachments of the muscles of the scalp and face.What are the cranial bones?
The eight bones of the cranium form the “vault” that encloses the brain. They include the frontal, parietal, occipital, temporal, sphenoid and ethmoid bones.

How does the skull protect the brain?
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles. … These bones protect the spinal cord.What is the function of the facial bones?
The facial skeleton serves to protect the brain; house and protect the sense organs of smell, sight, and taste; and provide a frame on which the soft tissues of the face can act to facilitate eating, facial expression, breathing, and speech.

What do you mean by facial bones?
n. Any of the bones surrounding the mouth and nose and contributing to the eye sockets, including the upper jawbones, the zygomatic, nasal, lacrimal, and palatine bones, the inferior nasal concha and the vomer, lower jawbone, and hyoid bone.
How do cranial nerves transmit information to the senses?
In general, sensory ganglia of the cranial nerves send out a branch that divides into two branches: a branch that enters the brain and one that is connected to a sensory organ. Examples of sensory organs are pressure or pain sensors in the skin and more specialized ones such as taste receptors of the tongue.
Which bone helps to form the face?
The facial bones (viscerocranium) make up most of the front of the skull. The bones responsible for the form of the face are – from top to bottom – the inferior nasal conchae and the nasal, maxilla, zygomatic, lacrimal, ethmoid, vomer, sphenoid, palatine, and mandible bones.
What makes up the facial skeleton?
The facial skeleton contains the vomer, two nasal conchae, two nasal bones, two maxilla, the mandible, two palatine bones, two zygomatic bones, and two lacrimal bones.

Which of the following is not a cranial bone?
Which bone is NOT considered to be part of the cranium? The lacrimal bone is a tiny bone found in the medial portion of the orbit. It is a facial bone, not part of the cranium.
Which of the following cranial bones is not a paired bone?
The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones. Although classified with the brain-case bones, the ethmoid bone also contributes to the nasal septum and the walls of the nasal cavity and orbit.
How many facial bones help make up the bony orbit?
The orbit appears as a quadrangular pyramidal cavern in the upper face. It is made up of four facial bones and three cranial bones: maxilla, zygomatic bone, lacrimal bone, palatine bone, frontal bone, ethmoid bone, and sphenoid bone.
Which part of your skeletal system protects the heart and lungs?
The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. The rib cage is one of the body’s best defenses against injury from impact. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.

Which bones protect the cerebellum and the brain stem?
After the parietal bones, there is the occipital bone at the base of the skull that covers the transition from the cerebrum to the cerebellum protecting the brain stem [Gray, 1974].
Which bone protects the brain from damage?
The brain is housed inside the bony covering called the cranium. The cranium protects the brain from injury. Together, the cranium and bones that protect the face are called the skull. Between the skull and brain is the meninges, which consist of three layers of tissue that cover and protect the brain and spinal cord.
Is cranium and cranial the same?
The bones in your skull can be divided into the cranial bones, which form your cranium, and facial bones, which make up your face. There are several types of bones within your body, including: long bones.
What part of the brain is the cranium?
The cranium—the part of the skull that encloses the brain—is sometimes called the braincase, but its intimate relation to the sense organs for sight, sound, smell, and taste and to other structures makes such a designation somewhat misleading.
